Nikita H.

Software Engineer | Java backend developer | Spring boot developer

I'm a Java engineer in love with the craft and ambitious and humble enough to keep learning every step of the way. Open to projects of any size, easy-going and flexible. My goal is to deliver clean and maintainable code right on time and grow professionally over the years to come. I'm sure we'll find a common language, you'll definitely be happy to see the tasks done right on time. A technical assessment or an iterview is always fine by me. My main tech stack: - Java8+ (Core) - Spring Framework (Core, WEB, AOP, Reactive) - Spring Security (Authentication, Authorization, OAuth2, JWT,Form Auth) - Spring Boot (Properties/YAML, Actuator) - Rest API bestpractice - SQL (MySQL, PostgreSQL) - NoSQL (MongoDB, FaunaDB, DynamoDB) - Spring Data (JPA, Hibernate, JDBC, R2DBC, MongoDB, ElasticRepository) - ElasticSearch - Spring Cloud (Cloud Gateway, Cloud Config, Cloud Circuit Breaker, Cloud OpenFeign, Eureka service registry) - Microservices - Microservice Patterns (Aggregator, Event Sourcing) - DevOps (Docker, Docker-compose) - AWS (S3, Lamda, Serverless, DynamoDB) - WebFlux - Message Queues (Kafka) - Testing (JUnit 4, JUnit 5, MockMVC, JpaTest, Testing Services, Fake patterns)
